. GHANNELING-MACHINE Specification of Letters Patent.

Application filed November'i, 1906, Serial No. 342,328, Renewed November as, 1910. Serial No. 55mm.

Be it known that I, WILLIAM G. MEYER, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Channeling-Ma chines; and I do hereby declare the-following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same. I I The present invention relates to improvements in channeling machines. i

v In t 1e manufacture of insoles for use on welted boots and shoes and of soles for turned shoes it is customary to prepare the margins-0f the insoles and soles for the re- CBPtIOIIOf the stitches by channeling, shouldering, slitting, and otherwise, and the object of the present invention is to produce an improved machine for so channeling and otherwisepreparing insoles and turned soles.

In its illustrated embodiment the invention is particularly adapted for preparing insoles of the type in which two flaps are cut from the surface of the material by a channeling knife and an edge-slitting knife respectively and arethen turned up and secured together to form a single compound lip.

- The invention consists in a channeling machine embodying the improved features of construction and operation hereinafter set forth, as defined in the claims.

In the drawings Figure l is a front elevation of a channeling machine embodying the present invention; Fig. 2 is a left-ban side elevation; Fig. 3 is a right-hand side elevation; Fig.4 is a plan view of the edge gage and its actuating mechanism; Fig. 5 is a detail plan view of a part of themec'hanism for rotating the work support; Fig. 6

The illustrated embodiment of the invention comprises a .-channeling-knife and'an edge-slittmg knifefor cutting "and turning up the flaps which form the lip on an insolo, a hammer for setting the flaps in their upturned; position and securing them together, a work support engaging the work Patented Feb. 21, "1911.

opposite to the knives, a four-motion feeding device engaging the work on the same sideas the knives, and-a movable edge gage for determining the distance ofthe lip from the edge-ofthe-insole.

The channeling knife, 1 consists of a square bar formed atits lower end, as shown in Figs. 9 and 11, with a horizontalcutting edge, and a vertical plow 2 which serves to turn up the flap cut by the knife. The charineling knife is mounted in inclined position in a roove in a knife block 3, being held therein by a clamp plate 4 fixed by a screw 5. An adjusting screw 6 engaging the upper end of the knife rovides for longitudinal adjustment thereo The knife block 3 is provided with a horizontal tongue 7 (Figs. 8 and 9)- engaging a horizontal roove 8 in the knife carrier 9, and is fii'ed in place by, a screw 10 engaging a slot in the knife block. This arrangement. permits horizontal adjustment of the channeling of the edge slitting knife provides for longitudinal adjustment thereof.

The knlfe block 12, is provided with a tongue 15 engaging a horizontal groove in the knife carrier 9, and is fixed In" place on the carrier by the screw 13. A presser foot 17 to limit the depth to which the knives enter the work is mounted upon the knife carrier. The presser foot has a shank 18 with beveled edges (see Figs. 8 and 9) by; which it is clamped in a presser-foot bloc 19 provided with a clamp screw'20. The resser-foot block has-a horizontal shank 21 secured to the knife carrier b a screw 22'engaging a horizontal slot in t e shank 21. An adjusti ng screw 23 engaging the shank provides for horizontal adjustment thereof to vary the distance betweenthe presser foot and the, knives. .The connect-ion of the presser foot with its block permits vertical adjustment of the presser foot to vary the depth of the cuts produced by the knives.

v The knife carrier 9 is mounted to yieldvertically to permit the knives and the presser oot to yield accordmg'to the thickness of the work, this being necesshry since 5 the work support, as will be presently'defl scribed; has no provision" for vertically. yielding. The knife carrier has a vertical plate 26. "A lug 27 extends forward from the shank and engages, when the'knife carrier is in raised position. owing to the insertion of an insole blank,

28- threaded 011 a rod 29 mounted in a lu'g '30 on the cover '1 plate 26. A compression spring 31 surrounding the rod 29 and ongaging the nuts 28 res ststhe ment of the lug '27 and the knife carrier, and operates to holdv the presser foot nor-- mally in engagement with the blank and the knives in. operative position. Adjusting nuts, 32 on the 'rodfl'29 serve to limit the movement of the rod 29 under the influence of the spring? 31. The downward move ment of the knife carrier is limited by a head; 33'0n the lower' end of the rod 29. The work support 35 consists ofaslightly convex circular table mounted upon astem 3036- (Fig. 3) which is'rotatably mounted in n sl ghtly inclined slide3j7. The slide 37 moves in a bracket 38 on thefront of the frame of the machine a and is provided at .its lowerend with ais 'journal'ed a bell having a depending arm 39 and clamp collar 34 on which crank lever I a normally horizontal arm'40.

The depending arm 39 is pivotally mountedwith a verticallink 41 pivoted at its upper end to the bracket 38. A spring 42 connected at one I end to thevlink 41 and at the other end-to the bracket to the position of Fig. lso as-to maintain the link and the arm 39 in lineandithe horizon. 11 arm in raised position, the upward movement of the arm 40 being limited I by a stop 43 on the bracket 38. When the parts are in this position the slide 37 and the work support are-maintained unyield-, 501

The n: workfsupport actuating means notclalmed' herein as it is claimed in an application 'formed by a division from this 1 fa'pplic'ation' and filed Sept. 22,,1909, Serial a s uitablc 1 "The four-motion feedingniechanismcomadjusting nuts upwardnioveend of the rock shaft position in a vertical [are imparted through an interpose 38 tends to swing the-link 41.

being in line, but when 40 is drawn down either to the left and ellcrank lever" of the cam lever 53; the

crank pin 50 ccentric ally mounted in the.

forwardend of the drive s'haft.51 of the machine. .The sl'eeve' 49 thus operates, as;

the drive shaft rotates, to impart lateral. movements to-the rod' 48, andto'move' the feeding device horizontally the vertical movements of the sleeve 4.9 not being transmitted to the 'rod and 'the feeding device. Vertical movements are'impai'ted to the rod 48 by mechanism comprising a cam 52 mounted on the drive shaft 51, a cam'lever 53 actuated thereby and fixed to 'a-rock shaft 54 journaled'ln the frame of the ma chine, and an arm 55 fixed to the forward 54 and'connected with the rod'48. .The arm'55 is pivotally con nected at- 56 Wli3l1 a sleeve 57 through which the rod-48' rises under'the influence of the cam lever 53 and cam 52 the sleeve 57 engages adjust- .ing nuts 58 on the rod 48 and raises the rod' and the feeding device. The downward movements of the rod and feedin device spring which permits the movement of the feeding device to be arrested byits engagement with the upper'surfaoepf the work, whatever the thickness thereof maybe. For

this purpose the upper portion of the rod 48 is surrounded by a sleeve 59 free to move longitudinally WItlJ' IQSPBCP to the rod and engaging at its lower enda compression spring 60. The lower end of the compression spring engages a collar 61 fixed on the rod 48. Theupper end of the sleeve 59 carries adjusting nuts -62 which engage the lower end of the sleeve 57 and limitithe relative underthe influence of the spring 69. Bv

"turningthe adjusting nuts 62 the sleeve Y may be rais'edor lowered todiniinish or increase the cpmpression of the spring .60.

When the arm 55 falls, under theinfluence rod 48 andfeeding' device fall until thelatter is pressed firmly agalnst the insole blank; and thereafter during the continued downward movement of the arm 55 the rod 48 remains vertically stationary while the sleeve 57 continues to descend, operating, through the adjusting nuts 62 and the sleeve 59, to compress the spring 60. The cam. 52 is so timed with respect to'the "crank pin 50 that the feeding device is first lowered toengage the work,

passes, and. when the arm movement of the sleeve 59 and .the rod 48 then moved horizontally to feed the work, then raised and returned horizontally to its initial position. A vyoke 63 connects the sleeve 49 with a sleeve 64 which embraces the sleeve 59 and acts as an additional guide to prevent cramping of the sleeve 49 on the rod 48. A pin 65 fixed in the sleeve 64 engages a flattened portion of the sleeve 59, as shown in dotted lines, Fig. 1, and prevents rotation of the sleeve 59.

Inorderto assist the four-motion feeding device in feeding the work, the work support 35 is made to rotate intermittently, in

. unison-with the feeding movement of. the

feeding device. portion of the-work-support stem 36 is embraced by a clutch ring 67 (shown particularly in Fig. 5). The clutch ring 67 is a resilient split ring provided with a lug 68 on which is pivotally mounted a lever 69. The lever 69 has a lug 70 engaging the free end of the clutch ring, and a spring 71 located in a recess in the lever 69 tends to maintain the lug 70 in engagement with the ring. The lug 7 0 operates to pinch the ring against the stem of the work support, the pressure of the ring against the stem depending upon the pressure of the lug against the ring. The end of the lever 69 is pivotally connected with a link 7 2 which is connected at its rear end'with a. cam lever 73 pivoted at 7 4:upon the frame of the machine. The cam lever 7 3 carries a cam roll engaging acam path 75 in thecam 52, and the cam path is so formed as to swing the lever 73 forward at the. time when the four-motion feeding device is feeding the work. This movement of thecam lever'causes the link 7-2 to swing the clutch lever 69 forward and rotate the work support by means of the clutch ring 67. The resistance to such rotation encountered by the work support causes-the lever 69 to pinch the clutch ring against the stem in proportion to such resistance, so that the clutch ring actspositively to rotate the work support during the forward movements of the lever 69, while the resistance of the work to reverse rotation of the work support causes the clutch ring to slide upon the stem during the backward movement of the lever 69. An arm '76 mounted on the upper end of the work support slide 37 provides at its end a bearing surface, as shown in Fig. 1, to

support the end of the clutch lever 69.

The use, in conjunction with a four-mm tion feeding device engaging one side of the work, of means for rotating the work support" which engages the other side of the work, renders the feeding of the work posi tive, and makes practical the use of knives operating with a drag out as in the present machine. in place of vibrating knives, thereby simplifying the mechanism of the operating p'arts.

The hammer 78 engages the upturned For this purpose the .upp'er the knife carrier. Owing to this'arrange;

ment the hammer occupies always the same vertical position with respect to the knives notwithsta'nding their rising and falling movements in response to variations in the thickness of the work, and thus the hammer always engages and operates upon the channel flap at the proper position. 'The hammer is vibrated toward and from the edge slitting knife by means of a rod 82 pivotally connected at 83 with a cam lever 84. The cam lever is pivoted at 85 on the frame of the machine and carries at its lower end a cam roll 86 engaging a cam path 87 in the cam 52. The rod 82 passes loosely through a hole in the lever 80 and is provided with adjusting nuts 88 which engage the lever 80 and move it forward to retract the hammer.

The operative movement is imparted to the hammer through a spring 89 engaging the lever 80 at one end and at the other end engaging adjusting nuts 90 on the rod 82. This spring permits the movement of the hammer to be arrested by its engagement with the work, so that the hammer hasa yielding action against the work. At each rotation of the drive shaft 51 the hammer strikes a plurality of blows against the channel flap,

thereby setting it in its upturned position and securing it to the flap cut by the edge slitting knife, the surface of the work being previously provided with cement for this purpose.

The distance of the lip from the edge of the insole is determined by the edge gage 91.

As shown in Fig. 4, the edge gage is provided with a toothed shank 92 engaged by a segmental gear 93 fixed to the upper end of a rock shaft 94cwhich is journaled in a bracket 95 mounted on the upper end of the work-support slide 3-7. The bracket 95 1s provided with'a horizontal shank 96 engaging a slot on a horizontal projection 97 from .the slide 37, and the shank 96 is adjustably fixed in position by means of a screw 98 engaging a slot therein and threaded into-the horizontal projection 97. The rock shaft 94 carries at its lower end an arm 99 having a forked end engaging a block 100 pivotally v mounted on a disk 101 fixed to the upper end of a rock shaft 102 (see Fig. 10). The rock shaft 102 is journaled in a sleeve 103 adjustably fixed in a" bracket 104E mounted onthe projection 97 from the work support slide 37. The lower end of the rock shaft 102 carries a head 105 to which is pivotally connected a hand lever 106 bvwhich the rock shaft 102 may be turned. When the rock shaft is so turned the block 100 swings the arm 99 thereby actuating the rock shaft 94, the segmental gear 93, and the edge gage 91. In channeling insoles it is customary tomined by the pin 107,. and for this purpose use three widths of margin, at the shank portion, the inside of theforepart, and .the

outside of the forepart respectively, and.

therefore three adjustable stops are provided for the edge gage todetermine its several operative posit-ions. A pin 107 projecting downwardly from the disk 101 engages a recess in the bracket 104:, as shown in Figs.

4 and 10, and limits the extreme forward p0 sition of the edge gage, whichv it occupies when channeling with the narrowest margin.

The adjustableconnection between the shank 96-and the part 97 permits adjustment of such extreme forward position as deteran adjusting screw 108 is provided, this screwbeing threaded'in'to' the part 97 and provided with a flange engaging the shank.

96 as shownin Fig? 3 to move the shank forward 'or back when the set screw 98' is loosened. for the purpose.- The intermediate position of the edge gage is determined by a latch 109 carried by the hand lever 106 and engaging a recess 110 in a flange 111 on the lower end of the sleeve 103. The position of this recess is adjusted by turning the sleeve 1 03, and-the sleeve is fixed in adjusted position by a clamp pi'n 112 provided at its forward end with a'lock nut 113. The latch 109 is held engagement with the recess 110 by a spring 114 'which tends normally to swing the hand lever 106 upwardly. By depressing the hand lever the operator releases the latch. The extreme rear position of the edge gage is determined by a clamp collar 115 which is clamped upon the disk 101 and carries a depending lug .116 (shown in dotted lines Fig. 1) which engages a corresponding stop117 on the bracket 104. This rearward position may be adjusted by loosening the clamp collar115 and rotating it on the disk 101. When the work support is lowered to insert a fresh blank phe edge gage moves downward with it so tiat when theblank is inserted it acts asa stop to determine the" position thereof. The mounting of the edgegage-actuating mechanism upon the work-',

support slide avoids the necessity of yielding connections between the edge gage and its actuating mechanism.

' To prevent rotation of the work support slide in the bracket 38 the slide is provided with a lug 120' (Figs. 2 and 4) which is "engaged by a vertical pin'121 fixed in the frame of the machine and passing loosely through a ,hole in the lug 120.

To operate the machine the drive shaft is set in motion and the work support is depressed bv the operator and a blank inserted between the work support and the presser foot. Thework support is then allowed to rise-and the operator guides the blank as it is fed throughthe machine, and at the juncturesbetween the shank and the inside and the outside of the forepart the operator moves the hand lever 106 to vary the width of the margin as is required.
